Aquí hay algo para comenzar:

from PyQt4 import QtCore, QtGui
class MyDialog(QtGui.QDialog):
def __init__(self, parent=None):
super(MyDialog, self).__init__(parent)
self.buttonBox = QtGui.QDialogButtonBox(self)
self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
self.buttonBox.setStandardButtons(QtGui.QDialogButtonBox.Cancel|QtGui.QDialogButtonBox.Ok)
self.textBrowser = QtGui.QTextBrowser(self)
self.textBrowser.append("This is a QTextBrowser!")
self.verticalLayout = QtGui.QVBoxLayout(self)
self.verticalLayout.addWidget(self.textBrowser)
self.verticalLayout.addWidget(self.buttonBox)
class MyWindow(QtGui.QWidget):
def __init__(self, parent=None):
super(MyWindow, self).__init__(parent)
self.pushButtonWindow = QtGui.QPushButton(self)
self.pushButtonWindow.setText("Click Me!")
self.pushButtonWindow.clicked.connect(self.on_pushButton_clicked)
self.layout = QtGui.QHBoxLayout(self)
self.layout.addWidget(self.pushButtonWindow)
self.dialogTextBrowser = MyDialog(self)
@QtCore.pyqtSlot()
def on_pushButton_clicked(self):
self.dialogTextBrowser.exec_()
if __name__ == "__main__":
import sys
app = QtGui.QApplication(sys.argv)
app.setApplicationName(''MyWindow'')
main = MyWindow()
main.show()
sys.exit(app.exec_())
